SI82A40BCE-IS4R

Isolators - Gate Drivers Overview

The SI82A40BCE-IS4R is a single-channel isolated gate driver from Skyworks Solutions, featuring capacitive coupling technology for signal transmission. It provides a peak output current of 1 A and supports an isolation voltage of 6 kVrms. The device operates within a supply voltage range of 3 V to 20 V and accepts both inverting and non-inverting logic configurations. Key electrical parameters include a maximum propagation delay of 31.4 ns, rise time of 8.3 ns, and fall time of 8.6 ns. It functions reliably across an extended temperature range from -40°C to +125°C and utilizes an SSO-8 surface-mount package.

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix IS4R against official Skyworks documentation to confirm reel packaging and moisture sensitivity level requirements. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity. Cross-reference the manufacturer part number with the latest datasheet revision to confirm compatibility with system voltage and isolation standards before finalizing orders.

Isolators - Gate Drivers Selection Notes

Select this component when a single-channel driver with 6 kVrms isolation and 1 A output current is required. The choice depends on the need for low propagation delay (31.4 ns max) and operation up to 125°C. Consider the SSO-8 package size for board space constraints. Verify that the application requires capacitive coupling rather than magnetic isolation for EMI performance.

Isolators - Gate Drivers Part Context

This device belongs to the SI82xx family of isolated gate drivers from Skyworks Solutions. The family utilizes proprietary capacitive isolation technology to provide robust signal transmission across isolation barriers. The SI82A40BCE variant specifically denotes the 6 kV isolation rating and single-channel configuration within this product line.

Isolators - Gate Drivers Replacement Considerations

Check Skyworks official substitution lists for direct replacements. Variants such as SI82A40ACE-IS4R offer similar specifications but may differ in isolation ratings or package types. Always verify pinout compatibility and electrical parameters before substituting.
